Myelin water imaging based on multi-echo CPMG sequence
is inherently slow, especially for high resolution in vivo animal studies. We hypothesize that using compressed
sensing with group-sparse reconstruction will significantly increase the
acquisition efficiency of myelin water images. CS accelerated myelin water
fraction (MWF) maps were simulated using fully sampled k-space data acquired
from excised rat spinal cords at 7T. MWF map quality was assessed and found
to be minimally impacted up to an acceleration factor of 2, making the
technique a promising approach at increasing acquisition efficiency in myelin
water mapping.
